SETH WHEELER, or. ALBANY, NEW Yoan. Leners Patent No. 87,450, (lated March 2, 1869.

Llfhe Schedule referred to in these Letters Patent and making part of the sama.

To all whomit 'may concern:

Be it known that I, SETH WHEELER, of the city and county of Albany, and State of New York, have invented a new and useful Improvement in Lever Horse- Powers; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, in which-.L

Figure l is aplan view of a horse-power having my improvement applied thereto. f

Figure 2, a'side elevation, aportion being shown in Section.

Like letters refer to corresponding parts in both figures.

My invention consists in applying a 4series of inde pendentanti-friction rollers, for supporting the master- Awheel and levers, said rollers being entirely disconnected frolm the master-wheel and frame of t'he machine, and pivoted to a detachedring, which serves-to maiutain them in their proper positions, while they receive the weight of the wheel upon their exterior, and not upon their axles.

As represent-ed'in the drawings- A is the master-wheel.

B B, the levers.

C, the frame in which the journals of the driving- E is the superior frame, furnishing the upper bear- 'ing for the same, while f K is a bevel driving-wheel on the central shaft, which is driven by the gears'D D D.

provide a circulantrack, F, of a diameter a little less than that of the periphery of the master-wheel,

.which is supported by stanchions, G, afixed to the frame C; and directly above, attached to the underside of the master-wheel, (heilig preferably cast on a portion of the same,) is an annular rib, h, corresponding with the track F. v

lhe rollers I I are interposed between these two A light ring, It, encircles the pulleys, and serves to keep them at suitable 'distances apart, they turning freely on'a pin or pivot fixed in said ring. y

'The object of this improvement is to support the weight of the master-wheel and its necessary adjuncts,

with as little friction as possible while revolving, which is-effectnally accomplished by this device.

. I au aware that the master-wheel has been sup# ported on rollers fixed to-staneliious upon the` frame, and such I do not daim, it not being new, and not accomplishing the same result which my improvement does, inasmuch as the great weight and strain brought upon the necessarily small journals ofthe pulleys, when fixed, soon causes them to wear out.

By vmy improvement, as the weight is supported wholl y upon the exteriors of the pulleys, which have no `journals, they are only subject to wear from friction upon the track, and act as simple rollers, beingkqnly held in positionby the fixed pins of the ring 7c, whi'dlrwf revolves as they roll.'

'lhey are thus rendered very durable, and support the wheel in a steady manner, reducing the draught by the amount of friction saved, and rendering it more uniform for the team.

I do not claim broadly supporting a master-wheel ou rollers; but

The series ,of independent rollers I, connected together by the rotating band k, on theoutside thereof, in combination with the master-wheel and the track F, substantially as and for the purpose described. l

In witness whereof, I have hereunto signed my name, inthe presence of two subscribing witnesses.

SEIH WHEELER.'
